Search in diphoton and dielectron final states for displaced production of Higgs or z bosons with the ATLAS detector in √=13 TeV pp collisions

A search is presented for displaced production of Higgs bosons or Z bosons, originating from the decay of a neutral long-lived particle (LLP) and reconstructed in the decay modes H -& gamma;& gamma; and Z -ee. The analysis uses the full Run 2 dataset of p
